Pixel
Set the pixel color interpolation method to use when looking up a color based on a floating point or real value.
When looking up the color of a pixel using a non-integer floating point value, you typically fall in between the pixel colors defined by the source image. This setting determines how the color is determined from the colors of the pixels surrounding that point. That is how to determine the color of a point that falls between two, or even four different colored pixels.

Divide area into two flat triangular interpolations
The color of the top-left pixel (floor function)
Fitted bicubic-spines of surrounding 16 pixels
A double linear interpolation of pixels (the default)
The average color of the surrounding sixteen pixels
The average color of the surrounding nine pixels
The average color of the surrounding four pixels
Unset value.
